In Drosophilia, the allele for normal length wings is dominant over the allele for vestigial wings. In a population of 1,000 individuals, 360 show the recessive phenotype.

The following four questions will lead you to the calculation of how many individuals you expect to be homozygous dominant and heterozygous for this trait?

1.) Based on the preceding information, which of the following genotype frequencies are you able to calculate?
A. Homozygous recessive
B. Homozygous dominant
C. Heterozygous

2.) The frequency of the homozygous recessive genotype is:

3.) Once you have calculated the frequency of the homozygous recessive genotype, what do you know about the allele frequencies?

4.) Based on the preceding answers, the allele frequencies in this Drosophila population are:

5.) Based on your answer to Question 4, the homozygous dominant and heterozygote frequencies are:

6.) Within this population, the number of individuals that you expect to be homozygous dominant and heterozygous for this trait are:
